Null pointer exception

I am trying to install my working app at a Java hosting center.  My app 
works fine on NT.  The app server is running Resin.  Cocoon 2.0.2 seems 
to be running ok.  When I try my app I get:


java.lang.NullPointerException

ok,  this was a stupid class path error.  I am now upgrading to 2.0.2 (i 
have been using 2.0.0) and having more problems.  I will post under a 
different subject.

Thanks,

Dan

According to 
http://cvs.apache.org/viewcvs.cgi/xml-cocoon2/src/java/org/apache/cocoon
/components/language/markup/LogicsheetCodeGenerator.java?annotate=1.11

Line 101 has only comment.

Something is wrong here, are you sure you have Cocoon 2.0.2? What's in
your copy of source code on line 101?
